Weather synopsis: January 24


10:40pm the weather across much of the eastern third of the nation has been rather soggy to say the least. A rather dynamic storm system has taken the place of the High pressure system that produced the fair weather on Friday and Saturday across much of the Northeast. Flood advisories have been issued up and down the eastern sea board where heavy amounts of rain is being observed and can be expected to continue. Regionally forecast rainfall could very well range between 1.0" across the interior to 3.0" along the coast. South of the region the heavy rain could be accompanied with some embedded thunderstorms, some of which could produce severe weather and locally heavier amounts of rain. The rainfall is forecast to dissipate from west to east across the region on Monday. This storm system is currently dragging a sharp cold front and with its passage temperatures will plummet through out the course of the week as an arctic air mass settles in. As the storm system pulls away and temperatures drop, wind orientation across the Great Lakes have the potential to produce lake effects snow showers for a good portion of the week. This arctic air mass combined with the current progressive weather pattern could yield a snowier time period ahead. NCEP forecast models seem to agree as data seems correlate with colder temperatures for the days ahead.
